Review: INKBIRD Temperature Controller ITC-308 – Climate Mastery at Your Fingertips

Climate Control for the home brewer, exotic pet owner or horticulturist

Established in 2010, INKBIRD has emerged as a pioneering force in the realm of smart IoT (Internet of Things) technology. This forward-thinking company has embarked on a mission to empower customers by seamlessly integrating cutting-edge technology into their daily lives. INKBIRD’s journey as a high-tech entity began a decade ago, and ever since its inception, it has remained unwaveringly committed to delivering top-tier smart home living products to its global user base.

A Product for the Goldilocks in You

In the ever-evolving landscape of technology, INKBIRD has steadfastly stayed ahead of the curve, consistently pushing the boundaries of innovation. With a visionary approach, the company has harnessed the power of IoT to create a range of products that not only simplify daily routines but also elevate the overall quality of life for its customers.

If you consider yourself Generation Z, the above reference might leave you feeling slightly bemused. You see, according to the fairytale, Goldilocks sampled the oatmeal belonging to three bears. She found the first bowl to be too hot, the second was too cold and the third happened to be just right. So, it could be argued that the third bear may have used the INKBIRD ITC-308 to regulate the temperature of his meal LOL. Okay, Goldilocks and the Three Bears is a work of fiction but the INKBIRD ITC-308 is very much real.

INKBIRD ITC-308: A Solution to Climate Change

Admittedly, this isn’t a solution to global climate change, but if you’re one of the hoards of home brewers, horticulturists, exotic pet owners or animal breeders, you will be more susceptible to temperature fluctuations than most. A shift in temperature of a few degree  could have serious repercussions on the outcome of a climate-dependant enterprise.

ITC-308: What is it?

The ITC-308 is a device that allows the user to set upper and lower limits to temperature settings. A “dual relay output temperature controller” as the marketing spiel says. It can be connected to both refrigeration equipment and heating equipment. The device has three leads that project from the base. The first is a power lead which obviously plugs into the mains socket. The second is a temperature probe which can be immersed in water/liquid or taped to an air conditioning unit. The third lead is an adaptor to which you can connect the plugs of a heating appliance and a cooling appliance. The ITC-308 will automatically switch the devices on or off as necessary to regulate the temperature. The Main ITC-308 body has a dual display set-up. This shows the current temperature and the target temperature.

Features & Settings

There are also buttons that allow the user to control the device settings to set up the device to meet their individual needs. For starters, you can opt to set the device to display the temperature in Fahrenheit (ºF) or Centigrade (ºC). Scrolling through the other settings will allow the user to set the following:

TS= Temperature Setting

HD= Heating Differential

CD= Cooling Differential

AH= Alarm High Limit

AL= Alarm Low Limit

PT= Compressor Delay

CA= Temperature Calibration

CF= Temperature Value

SV= Setting Value

While the device can be programmed to maintain the temperature at a given setting, it is also possible to set tolerance values outside of which an audible alarm is activated to alert the user if the temperature increases or falls below the set levels. The user can also set a “Compressor Delay” which specifies a period of time after which the device can swing into action following a breach (higher or lower) of temperature.

Fancy a brew?

Those who know me will know that I’m a lifelong teetotaller so the consumption of alcohol is a no-no for me. I also happen NOT to be a keen horticulturist or exotic pet owner. So testing the INKBIRD ITC-308 was a challenge that I was determined to face for the benefit of the discerning readers of this review.

I have a friend who is a keen Kombucha brewer. He and his wife swear by the stuff extolling the virtues associated with this purportedly healthy drink. I prefer to remain on the fence on this issue however. Kombucha, for those who don’t know, is a fermented tea-based drink that has grown in popularity among health-conscious, groovy, hipster folk. I had a swig of it and let’s say that it was an “interesting” experience. Now, I won’t go through the whole brewing process but it’s vital to keep the optimum temperature between 75-80ºF (24-26ºC) for the mixture to brew properly over a period of a few days. Failing the fermentation process will result in a concoction of a vinegary beverage that will assault your senses (and stomach too perhaps). As the production process involves sugars and yeast, it requires the promotion of healthy, beneficial micro-organisms. If the temperature isn’t kept just right, this could result with a weaker strength drink (if too hot) and a prolonged fermentation time (if too cold).


INKBIRD’s dedication to excellence has earned it a well-deserved reputation as a leader in the smart home industry. Through meticulous research and development, as well as a commitment to quality craftsmanship, INKBIRD has successfully crafted a portfolio of products that seamlessly blend functionality, convenience, and aesthetics. These products have not only transformed homes but have also revolutionized the way people interact with technology on a daily basis.

The INKBIRD ITC-308 has earned a good reputation in recent times among its users for good reason. It’s a feature-rich device that is also quite reasonably priced. Whether you’re a home-brewer, a vivarium (I had to look that word up!) or an aquarium owner, this device will allow you to create a harmonious climate for fermentation, incubation and habitation.

With a global presence, Inkbird’s impact is felt far and wide, touching the lives of users from diverse backgrounds and regions. The company’s products have bridged the gap between tradition and innovation, making it possible for individuals to embrace the future while cherishing the essence of home.
